- Lie on left side next to a wall with back facing the wall, head resting on left hand, right hand on floor in front of body for balance. Extend legs forward so that they're slightly in front of body.
- Press right heel back against wall behind you, foot flexed with toes pointing forward. Keeping hips and shoulders squared forward, keep pressing heel against wall as you slide foot up as far as you can. Lower leg (still pressing heel) to start position.
- Do 10 reps, then switch sides and repeat.
Trainer's Tip: If your hips shift forward during the leg lift, you've gone too high.
